Obviously, small sample size caveats apply for all the playoff numbers.
The point here isn't to attempt to directly compare Pietrangelo and Shattenkirk. There really isn't any comparison to be made there. Different players, different usage. Pietrangelo's numbers are just there as a measuring stick of sorts.
The point here is to remind people of what Shattenkirk has historically brought to the table. There's no arguing that Shattenkirk was (uncharacteristically) bad this year. Let's not let recency bias taint our memory of what he's provided in the past, in either the regular season or the playoffs.
